It's way cute! Go ahead and finish it the way you started and just know it's the way it's supposed to be--unique. Sometimes our "mistakes" end up being the best art and the things we remember with a smile.
My grandmother taught me to sew and quilt, and she said, "Only God can do Perfect, so just work around or through your mistakes and say it was on purpose." That was years ago, and I still think of her saying that every single time I sit at my sewing machine.
